Procedure
    +

  1. The MTM that needs to +restore message data from message store in chunks should get the CMsvPlainBodyText object +using the InitialisePlainBodyTextForReadL() method of CMsvStore.

    2. +

  2. Set CMsvStore to +the ID whose body text needs to be stored, and open it in the read mode.

    3. +

  3. Use any of the following CMsvPlainBodyText::NextChunkL() methods +to get the email message in chunks:

      +

    1. TDes8 &aChunk

      2. +

    2. TDes8 &aChunk, TRequestStatus &aStatus

      3. +

    3. TDes16 &aChunk

      4. +

    4. TDes16 &aChunk, TRequestStatus &aStatus

      5. +

    The length of the chunk to be restored in a single call to NextChunkL() is +decided by the MTM, when it initialises CMsvPlainBodyText for +the read operation.

    The email application can call NextChunkL() until +the length of the chunk populated by NextChunkL() is 0.
    4. +

  4. The retrieved message +data can be sent by the MTM in chunks.

    5. +
The MTM can also use the existing CMsvStore::RestoreBodyTextL() method +to retrieve the entire body text in a single operation. To do this, the plain +text body of the email message, which is stored in the message store, will +be copied to the CRichText reference and passed to RestoreBodyTextL().
